NASA finds humanity would totally fumble asteroid defense
(www.theregister.com)
This is a most excellent place for technology news and articles.
"According to The Atlantic, an asteroid that weighs more than 1.7 quadrillion metric tons could sterilize Earth by raising the temperature of its water above 100°C. This asteroid would be 10–1,000 times heavier than the asteroid that killed the dinosaurs and would be between 60–96 kilometers (37–60 miles) wide."
The Atlantic article itself is paywalled, but yes, and it's entirely dependent on the mass of said Asteroid.
i'm not worried because an android that heavy couldn't even stand up
Id imagine it doesn't have to really move fast, just has to sit in the right spot and wait for our orbit around the sun to smash us into it?
